The beluga whale is a medium-sized marine mammal known for its distinctive white color and rounded forehead. They are found primarily in the Arctic and sub-Arctic regions, often inhabiting shallow coastal waters. Belugas are social animals, living in groups called pods, and are known for their vocalizations, which have earned them the nickname "canaries of the sea." Belugas can grow up to 18 feet long and weigh as much as 3,500 pounds. They primarily feed on fish, crustaceans, and other marine organisms. Unlike many other whale species, belugas do not have a dorsal fin, which helps them navigate icy waters more easily.
